Thanks anyone for the replies.
In case anyone else encounters the problem:
I solved the issue "brute-force" by resetting all the Preferences to
their default value (hold Shift+Option keys down at Mathematica
start-up, on a Macintosh).
So most probably the cause was an obscure preference toggled
unintentionally, although I don't know which and how.
